    Design and Experimental Study on Divergent Magnetic Fluid Seal with Large Clearance and Dual Magnetic Sources by Xiaolong Yang, Yunyun Song, Peng Sun, You Li

    Published 2022-01-01
    “…In order to solve the leakage problem of rotating machinery under the condition of large clearance, a new type of divergent magnetic fluid sealing device with secondary magnetic source was designed. The magnetic field distribution in the clearance of the magnetic fluid seal was simulated by the finite element method of magnetic field, and the theoretical value of the sealing pressure resistance was calculated according to the pressure resistance theory of the divergent magnetic fluid seal. …”

    Enhancing stochastic optimal power flow with modified cheetah optimizer for integrating renewable energy sources by Majid Saeidi, Taher Niknam, Mohsen Zare, Zulfiqar Ali Memon

    Published 2025-04-01
    “…Abstract In this paper, a modified cheetah optimizer (MCO) algorithm is presented, which has been designed to address the optimal power flow (OPF) problem in power grids that utilize renewable energy sources (RES). The issue of uncertainty in cost models for wind turbines (WTs) and photovoltaics (PVs), which can result in overestimation or underestimation of RES, is addressed by including the uncertain cost value in the direct cost of these renewable units to calculate their cost value accurately. …”

    Insights into the effects of geographical sourcing area on nutrient composition and sensory attributes of nine edible insects by Jackson Ishara, Rehema Matendo, Jeremiah Ng’ang’a, Saliou Niassy, Karume Katcho, John Kinyuru

    Published 2025-04-01
    “…A principal component analysis (PCA-Biplot) indicated that the two axes accounted for up to 97.7% of the observed variability in the nutrient composition and sensory attributes of commonly consumed edible insects sourced from different geographical area. Visualized results after cluster analysis using non-metric multidimensional scaling (NMDS) indicated that the geographical sourcing area has substantial and significant effect on the nutrient composition as well as sensory attributes of the studied commonly edible with a stress value of 0.185.…”

    The armour of the common soldier in the late middle ages. Harnischrödel as sources for the history of urban martial culture by Regula Schmid

    Published 2017-12-01
    “…Although the results of this analysis are only preliminary – at this point, it is not possible to produce methodologically sound statistics –, the value of the lists as sources is readily evident, as only a smattering of the once massive quantity of actual objects has survived down to the present time.…”
